Make python socket asynchronous?

由 我只是一个虾纸丫 提交于 2019-12-11 10:02:16
问题 I have the following script and I'm trying to make it asynchronous. It works fine as a client to connect through TCP and send the text file. However, I'm executing it from another software program, and it is slowing down the program I'm running it from (hence the need for async). My aim is to get the script to run in it's own background thread, so that it doesnt affect the program it is being executed from. I've tried adding asyncore, but I just keep getting errors and it wont seem to connect

问题 I am using python asynchat to implement a network protocol. At connection time I need to send a command and the server answer with a session. My main problem is that I need to wait until I get the session response. but not sure how to implement this. should I use socket.recv for the connection setup? is a good idea? 回答1: When writing a network application using asynchronous techniques, you wait by recording your state somewhere and then letting the main loop continue. At some future time, the

Python - Asyncore (client) socket - Can not determaine connection status

由 时光毁灭记忆、已成空白 提交于 2019-12-10 11:54:59
问题 For some reason, self.connected of the asyncore.dispatcher class doesn't consider my socket to be connected on the client side. The server side sees the socket as connected and treats it as such, but the client doesn't know if it's connected or not and handle_connect doesn't "proc", so i can't use a overridden version of it to check if the socket is connected either. Any thoughts on this code why it ain't working: #!/usr/bin/python # -*- coding: iso-8859-15 -*- import asyncore from threading

问题 I have the following situation: SomeServer(S) <-> (C)MyApp(S) <-> (C)User (S) represents a server socket (C) represents a client socket Essentially, MyApp initiates communication with SomeServer ( SomeServer(S) <-> (C)MyApp ) and once some authentication routines are successful MyApp(S) starts waiting for ( C)User to connect. As soon as User connects, MyApp relays data from SomeServer to User . This happens in both directions. I have SomeServer(S) <-> (C)MyApp working perfectly, but I'm not

问题 I wrote a asynchorous client using python asyncore, and met some problems. I have solved this with the help of this: Asyncore client in thread makes the whole program crash when sending data immediately But now I meet some other problem. My client program: import asyncore, threading, socket class Client(threading.Thread, asyncore.dispatcher): def __init__(self, host, port): threading.Thread.__init__(self) self.daemon = True self._thread_sockets = dict() asyncore.dispatcher.__init__(self, map

python asyncore keep track of clients

I'm writing a simple socket server and I want to keep track of the clients state (authentication and stuff). Every time handle_read() is called I don't know anything about that particular client. It would help if I knew the ID of the client or something. Here's what I have so far: import asyncore import socket class EchoHandler(asyncore.dispatcher_with_send): def handle_read(self): data = self.recv(8192) self.send(data) class EchoServer(asyncore.dispatcher): def __init__(self, host, port): asyncore.dispatcher.__init__(self) self.create_socket(socket.AF_INET, socket.SOCK_STREAM) self.set_reuse
